IMPRCVED vCARRIAGE-il'ACK The Schedule referred to in these LettersPatent and making part of the, name.

+41 To all Iwhom it ma/y concern Be it known that I, J. NEWTON THATCHER,of Martinsburg, in the county of Berkeley, and State of West Virginia,have invented a new and improved Wagon-Jack;A and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art to make 'and use the same,reference being had to the accompanying drawing, forming part of thisspecification.

This inventionI relates to improvements in' jacksforraising-cai'riage-wheels oi the ground, 'to facilitate the renoval ofthem for lubricating and other purposes.'

It` consists in the arrangement, upon a suitable crum on the said stand,for vehicles of diierent heights, and a holding-bar, for holding thelever when the vehicle has been raised up, all as hereinafter fiillyspecip The drawing represents a side elevation of my improved jack,supporting a wheel in the elevated position.

Arepresents a stand, having a foot, B, considerably 'elongated in thedirection C.

D represents an elevating-lever, having a fulcruiu in the top of thestand, which may be adjusted vertically or longitudinally.

Also, a notch, or groove, E, in the end of the short arm, wherein theaxle of the vehicle is designed to rest.

The long arm of the lever is provided with a metallic loop, F, at oneside, wherein the free end of a holding-har, G, slides, and'on to whichit catches by means of a notched bar, H, secured thereto. The otherrendof the said holding-bar is jointed to the foot B.

In swinging down the long arm of the lever D, to raise an axle, the loopF will slide along the holdingbar, and the notched bar will catch uponthe loop and hold the lever D down.

The elongation of the foot B, at O, beyond the length of the short arm,prevents the stand from falling over in that direction, and the wheel,opposite to that raised, prevents falling laterally.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The combinationwith the stand A, havingv an elongated foot, of the lever D, notchedholding-bar G, and loop F, all substantially as specified.
